摘要:
“一锅法”Mannich反应制备β-胺基酮类化合物在医学制药和生物碱的合成中广泛应用,寻求一种高效、腐蚀性和环境污染小的催化剂一直是该反应的研究热点.文章研究了四氯化锡催化“一锅法”Mannich反应,考察了四氯化锡对催化反应活性的影响,以及对不同反应底物制备β-胺基酮类衍生物的适应性.研究表明,芳香胺或醛的对位有硝基取代基时反应时间缩短,产率明显提高.常温下,无水乙醇作溶剂,SnC14作催化剂,产率最高为85.8%.

摘要:
In this paper, it was studied that using stannic chlo-ride, 1#pure tin and deionized water as the material to prepare stan-nous chloride. Focuses on the influence of the reaction temperature, reaction time, tin excessive amount to stannic chloride conversion rate. The results prove that: (1) When the reaction temperature is higher than 110°C, the conversion of stannic chloride along with the rise of temperature increase, but after 105°Cisnot obvious;(2) Rea-sonable response time is2.5 h;(3) The best tin excessamount is3%.%本文介绍以四氯化锡、1#精锡和去离子水为原料制备氯化亚锡的工艺研究,重点考察了反应温度、反应时间、锡过量量对四氯化锡转化率的影响。研究结果表明:(1)在反应温度为<110°C时,四氯化锡的转化率随温度的升高而提高,但105°C以后提高不明显;(2)合理的反应时间为2.5h;(3)最佳的锡过量量为3%。

摘要:
研究了En(IdH4)2ZrCl2负载到硅胶载体和SnCl4修饰的硅胶载体、以甲基铝氧烷为助催化剂时的乙烯聚合反应。实验结果表明,在n(Al):n(Zr)=3 000、聚合温度为60°C时,SnCl4修饰的硅胶载体负载的茂金属催化剂体系的聚合活性达到最高,与相同聚合条件下均相催化剂体系的聚合活性相近。XPs分析结果显示,SnCl4修饰硅胶载体负载的茂金属催化剂体系中Zr原子的3d5/2结合能要高于硅胶负载的茂金属催化剂体系,使其具有更强的阳离子特征,从而提高了催化活性。

摘要:
According to the principles of simultaneous equilibrium and electronic charge neutrality, the thermodynamics in the system of SnCl4-NH4CI-HCl-H2O at normal condition has been calculated. Relation between all sorts of complex of Sn4+ and pH has been plotted. Based on thermodynamics analysis and calculation, some experiments was done to validate the relation between the total concentration of tin ion and pH in this system. Results suggest that the total concentration of ammonium and pH are the most important factors which determine whether (NH4)2SnCl6 or Sn(OH)4 exists in this system. Results further suggest when [HCI]≥6mol·l-1,Sn4+ in this system will be also precipitated in the form of (NH4)2SnCl6.These results lay the solid theory foundation to prepare pure (NH4)2SnCl6,a promising substitution for SnCl4·5H2O to prepare antimony doped tin oxide(ATO) and indium tin oxide(ITO),from the tinny material.
